“…Like the ash content, a sharp increase in the concentrations of Cu, Pb, Cd, Zn starts with a depth of 125-150 cm, which corresponds to the first half-middle of the XIX century and is consistent with the history of industrial development in Western Europe. The first stage of this dramatic increase is related to an increase in the number of burned coal and increasing the volume of melted metal since 1850 and the secondwith the use of lead in gasoline in the period 1970-1990 [14].…”

“…, but enhanced input of heavy metals can be identified also in topsoils of mainly agricultural regions (Martin 2000;Desenfant et al 2004;De Vleeschouwer et al 2009;Kadlec et al 2009;Grygar et al 2010) and even at sites very remote from local sources (Renberg et al 2001;Novák et al 2003Novák et al , 2008. Actually, in these "cleaner" regions, the major input of heavy metals, in particular Pb, has been a result of long atmospheric transport and hence it reflects larger-scale sources (Renberg et al 2001), more geographically smoothed and attributed to broader societal processes, such as massive introduction of coal burning in Central and West Europe (Weiss et al 1999;Renberg et al 2001;Novák et al 2008) as the main energy source in the nineteenth and early twentieth centuries.…”

Regional contamination by Pb and Zn in southern Moravia (south-east part of the Czech Republic) in the twentieth century was analysed in Brno Dam lake sediments and in floodplain sediments of the Morava River near Strážnice. The age model for the Brno Dam lake sediments has been obtained by 137 Cs (maxima corresponding to the nuclear tests in atmosphere and the 1986 Chernobyl accident) and the construction of the dam (1940); the time constraints for the Morava River sediments was the erection of flood defences (1930s) and 210 Pb dating. In the case of floodplain sediments, profiles exhibiting post-depositional mobilisation of heavy metals by pedogenic processes (gleying) must be excluded to reconstruct the history of contamination. There was a relatively fast joint onset of Pb and Zn load since the early stages of industrialisation in the first half of the twentieth century, but then the concentrations of these two metals developed in a different manner. Pb load only slightly increased till its peak in 1960s and 1970s. The increase of Zn load was rather stepwise: Soon before 1930s (Morava River floodplain) and in 1940s and 1950s (in Brno Lake), the relative contamination by Zn was much lower than during its peak in the 1970s to the present days. The offset of Pb and Zn contamination curves could have been caused by three different artificial sources of these heavy metals. The temporal shift of Pb and Zn loads can be used for dating sediments.

“…Since the middle eighties, ombrotrophic peat bogs have been dated using 210 Pb in various locations in the world (e.g. Holynska et al, 1998;Shotyk et al, 1998;Turetsky et al, 2004;Le Roux et al, 2005;Mizugaki et al, 2006;De Vleeschouwer et al, 2007;Ali et al, 2008;Lamentowicz et al, 2008;Novak et al, 2008;Olid et al, 2008;De Vleeschouwer et al, 2009), mainly using a Constant Rate of Supply (CRS) model first developed by Appleby and Oldfield (1978). In terms of environmental reconstruction in peat bogs, several studies have, for example, showed that combined with elemental geochemistry and non radioactive lead isotopes, 210 Pb was a powerful technique to evidence the industrial revolution through Europe, as well as the introduction of unleaded gasoline (e.g.…”

Development of Lead-210 Measurement in Peat Using Polonium Extraction. A Procedural Comparison

2010

Abstract:Two chemical treatments for lead-210 measurement were compared on the sub-surface samples of a core from an ombrotrophic bog from East Belgium. The classical procedure involves a concentrated acid extraction of polonium. However, this treatment represents substantial health risks together with unknowns regarding both the degree of cleanliness and the Po extraction rate, and most importantly, is rather time consuming. We developed here an improved procedure involving an ashing step prior to acid extraction. This allows substantial improvements such as: 1/ the use of a relatively small amount of acid compared to the classical procedure and 2/ the substantial reduction of a total sample digestion time. Measurements of 210 Pb concentrations were conducted by alpha spectrometry. Results show a good agreement of unsupported 210 Pb activity obtained for both procedures, although some unknowns remain concerning the adsorption of 210 Po on the plastic test tube, the volatilization of a small amount of ash, or the absorption of alpha particle at the alpha source surface. This however should not affect the 210 Pb measurement as all the samples are spiked prior to ashing (i.e. the recoveries are fully monitored). Through this study, we are suggesting researchers to follow this new procedure in order to increase safety, cleanliness, better recovery and substantial time gain.
